344- Transactions. — Botany. 



Schcenus axillaris, Br. — Ohinemutu, &c., the most southern locality yet recorded. 



Eleocliaris sphacelata, Br. — Rotorua, Rotomahana, etc. ; the most southerly 

 habitat yet recorded ; Lyall's habitat of Bluff Island for this species is 

 probably erroneous. 



Isolepis aucklandica, Hook. f. — Attains its northern limit at about one mile 

 east of Otumakokori ; altitude, 1,500 feet. 



Fimbristylis dichotoma, Vahl. — Attains its southern limit at Botorua, in the 

 modified temperature produced by the hot springs ; with increased 

 facilities for travel it will probably become established about all the hot 

 springs in the Taupo country, as is already the case at Otumakokori. 



Cladium ai'ticulatum, Br. — By Lake Taupo, the most southern locality 

 observed; altitude, 1,200 feet. 



C. junceum, Br. — Probably common throughout the North Island at least, 

 but has not yet been recorded from any locality south of the lake district. 



Lepidosperma concava, Br. — Attains its southern limit at Orakeikorako. 



Sporoholus elongatus, Br. — Observed as far south as Lake Taupo. 



Deschampsia ccespitosa, Palis. — Attains its northern limit at Botorua. 



Gleichenia dichotoma, Willd. — The accessory pinnae are remarkably developed 

 in some of the Botomahana specimens ; entirely confined to steaming, 

 heated soil. This was first discovered at Botomahana by Captain Gilbert 

 Mair, who informed me that it grew sparingly about hot springs at Matata, 

 on the East Coast ; it occurs abundantly at Botomahana and Otuma- 

 kokori, in profusion about Orakeikorako, and again by some hot springs 

 near Tapuaeharuru ; also, I believe, sparingly about hot springs at 

 Tokano, near the southern extremity of Lake Taupo ; so that it has been 

 found in scattered localities along the entire line of volcanic action, and 

 is not so absolutely local as is commonly supposed. 



Dicksonia antarctica, Br. — Common in forests between Maketu and Ngongotaha. 

 Captain Mair informed me that he had seen specimens growing between 

 Katikati and Ohinemuri, which doubtless mark its northern limit on the 

 East Coast ; and I learn from Mr. W. J. Palmer that a solitary specimen 

 occurs about seven miles due west of Ngaruawahia, which will prove its 

 northern boundary on the West Coast ; where, however, its rarity is 

 attested by the fact that the fern itself was quite unknown to Waikato 

 natives who accompanied Mr. Palmer. 



Asplenium colensoi, Moore, appears to find its northern limit at Motukino; 

 altitude 1,500 feet. 



Nephrodium molle, Desv. — Only found about the boiling wells and River 

 Otumakokori. The Botomahana habitat given in the " Handbook " is 

 certainly an error, and I believe that Mr. Robert Mair's Whangarei 

 plant must be referred to some other species.
